Y inf-inaccurate, or ORLANDO, mamas GUARD-RAIL} 03am:

T 0 all whom it may concern Be it known that I, WILLIE L. DApeH'rRY, acitizen of the United States, residing at Orlando, in the county ofOrange and State of Florida, have invented certain new and usefulImprovements in Guard-Rail Chalrs, of which the following is aspecification.

This invention relates to improvements in guard-rail chairs,particularly upon the subject-matter as embraced in my pendingapplication, filed August 4, 1920, Serial No. 401,197.

The characteristic feature or polnt of difference of the presentinvention or improvement over my co-pending or companlon case consistsin providing the integral base member with an upstanding lug or portionupon the off side of the guard-rail, said upstanding portion or lughaving an undercut recess or slot intermediate the resultant shoulderformed in the lower part of said lug and the integral base member forthe reception of the guard-rail flange. The base member is extended, asin my co-pending case, to provide for the support of the track rail butis devoid of the opposite undercut recess or slot of said companiondevice, a stop without a slot being substituted-therefor, said lug,however, having assoclated therewith a tapering key insertible into acorresponding passage in said lug. Also in my present invention orimprovement, I employ a clamp plate adapted, in connectlon with saidkey, by subjecting the latter to a driving action to impart a clampingaction of said clamp plate upon the rail.

The invention, therefore, consists of the structural features andinstrumentalities as above pointed out and defined in the appendedclaim.

The accompanying drawing illustrates the preferred embodiment of' myinvention, wherein it will be understood that various changes andmodifications as relate to the detailed construction and arrangement ofparts without departing from the spirit or scope of my invention ascovered by the 7 claim, and in which drawing Figure 1 is a plan view ofrailway rails showing the application for use of my invention thereto.

Fig. 2 is a vertical section of the same.

Fig. 3 is a detached perspective view of my guard-rail chair.

Specification ofLetters P atent. Pate t u 14, 1921,

Application filed November 17, 1920. Serial No. 424,709.

Fig. 4 is a plan view thereof.

Fig. 5 is a detached perspective of the clamp plate.

In carrying out my present invention, I provide, as in my co-pending orcompanion case, a base member 1 and said base member with an upstandinglug 2, but, instead of forming said lug with a plurality of undercutslots, I provide said lug in the present instance with a single slot orrecess 3 only, for receiving the base flange of the guardrail, asclearly shown. Also, the upstanding lug 2, in my present improvement,has a passage or key-way 3 extending entirely through said lughorizontally, said passage or key-way being tapered toward one end. AlsoI provide in connection with said base member and its lug 2, a key 3 ofcorre spondingly tapered contour as said passage or key-way, the smallerend or terminal of said key projecting beyond said lug and provided witha transverse orifice 3 adapted to receive preferably a cotter pin 4toprevent the accidental displacement of said key. Further, I employadditionally a clamp plate 5 which is interposed or insertedintermediate the lug 2 and the guard rail to cooperate with said key 3for effecting the clamping action of plate 5 upon the track rail. Theclamp plate 5 is provided with lugs 5*, one arranged at each of itsupper corner edges, the normal position thereof being vertical, toprovide for the retention of said plate against accidental lateral orendwise displacement. It is to be understood that as a hammering ordriving action is delivered to said key, the pressure thus exerted uponthe clamp-plate 5, will effectively secure the clamp-plate against theweb of the guard-rail, as seen particularly in Fig. 2, which willcotiperate, with the contacting of the base of the guard-rail with thatof the track-rail, to firmly seat or secure the guard-rail in place.

I claim and desire to secure by Letters Patent:

In a guard rail chair of the type described, a base-member having astop-shoulder for the base of the track-rail, and an upstanding lugspaced off from said stop-shoulder and having an undercut recessreceiving a lateral edge of the base of the guard-rail, said upstandinglug also having a slot in its inner wall above the undercut recess, saida clamp having arms at its ends adapted to clamp against the guard rail.

slot tapering longitudinally toward one end, ing the key against saidclamp and said extend laterally of said upstanding lug and Intestimonywhereof I aflix my signature retain said clamp against longitudinaldisin the presence of two witnesses.
